This invention relates to a slide-buckle and has gaged frames disposedrin a face-to-face substan- K tiallyrparallel relationin .which the frames are provided with side bars and cross bars connecting the side bars for deiining openings therethrough, the frames having a strap threaded therebetween with the free endthereof extendingbeneath the overlying frame. The frames are provided with means-for directing relative movements thereof to clamp the strap in desired adjusted positions, there being means on one of the cross bars of the overlying frame extending in the direction of the other crossibar thereof to YVdetachably receive a supporting member andto retain the free end of the-strap Yagainst displace- "rnent'.

' The device ofthe present invention is adapt- 'ticularly on the person and may be employed with slight 'variations not departing from the spirit of-'this invention, universally where detachable connectionsV are desired to be made. However, in the drawing and in the following description, the slide buckle will vbeshown and described in its association'withY the strap 'of an overall, the strap Ybeing lthreadedbetween the frames with relative movements of theframes clamping the strap in adjusted positions-*One of the cross bars 'of the Y'overlying frame of the buckle is .provide'd'with means extending in the direction of the other cross bar thereof for detachably receiving a ring or other supporting member of a bib of an overall andgfor retaining the Yfree end of thestrap againstdisplacement.`

It will, of course, be readily apparent that the buckle may be variously employed and that this invention is not to be limited to the specific uses hereinafter described and illustrated.

One of the objects of this invention is to provide a buckle comprising al pair of slidablyiengaged frames of the type hereinabove described in` which the strap threaded therethrough may be conveniently and easily adjusted irri-either direction@4 i r- A further object of this invention is to pro- Vvide a strap-engaging buckle'comprisinga pair of slidably engagedirames of the character `able for use' with various Vtypes of objects par-y above notedin which'the, means for detachably` "receivinga supporting member is disposed on one ofthe crossvbarsvand extends in a direction toward4 thebther cross bar of the frame in order .that the freeend'of the strap may be held against displacement; j l f y VAstill further object of this invention is to provide a slide buckle comprising a pair of slid- Vably engaged'frames-of the type indicated above in which: the constructionQmay be relatively inexpensive'to manufacture-may be durable and simple in construction, and simple in threading ,and manipulationi t y' Other objects and advantages will hereinafter be ,more particularly pointed out and for a more completehunderstanding ofth'e" characteristic i 'features'ofthis invention, reference may now be hadt'o Vthe-followingdescription `when taken together' with the accompanying drawing, in which latter: 'f L "Figur lisa fronti elevational view vof one .form'of buckle embodying thefeatures of this invention, thebuckle being attache'd'to a fragmentaryfporti'on of a shoulder strap. for su-pfporting a fragmentary portion of the bib of an `overa1l;* f t 't Y Fig.2 isa. central longitudinal sectionalrview H taken on the 1inet2'-2 of Fig. 1 showing the strap 1in kalcltmiped position-between the slidably engaged frames 'of the buckle;

yReferringvnow' to the drawing and more particularlytoiigs; lfto 6,-'inclusive, thereof,` the f constructionxthereinf shown comprises a pair of frame members `I5 and IG, the frame member l5 being :preferably substantially rectangular in g-ioutline andyhaving :sideybars I1 and I8 con- `'nectedftogether. by crossrbars `l!) and 20. 'I'he inclined portion 25, are likewise inclined in the, v

same direction as portionj but at a greater Y angle to accommodate the usual thickened edge portions of a strap 28. The side bars and cross bars ofthe frame l5 are preferably formed of a relatively Ythin sheet of material and thus are shown as being embossed, or, in other wor-ds, a peripheral flange is disposednover thebuckle frame. ,Y Y p The other cross bar 20 of the frame I5 is provided Witha pair ,0f bcbk-shanedfproiectine p0rtions. 29. and 30. `which.entend initially. outwardly and then in. the direction Qf. .the other-.ClOSS bal t9. for cofceeration. wtha tongue .3 I. extending .in a direction towardthe hook-shaped portion to reieasably closethe opening, .tothe hook-.Shaped member.; ,-'iheiframe .1.5.1.beinanreferably fermed of relatively thinlsheet metal, providesa desired resiliency in Vthe tongue portion 3 I, the tongue being formed preferably integrally with the cross bar I9 yand extendingrom the .inclined Strapengaging facev2I thereof. The .tongue 3l: overlaps atleast a portionpfthe faces of Ithe hook-shaped portions 29 ,and 3U` to, close the Avopening thereinto vand is preferably out frpnrthefmaterial between the hook-shaped, members 29v Aand 30,thelatter being .cut from materialsurrounding'the tongue andl being thereafter AbentY inwardlyy in a ,direction toward each other to overlie the tongue.

A'. strap-engaging slotv V32v is formed by the spaced side bars .andcross bars ofthe frame I6, theframe being reenforced by. the :provision of a flange 25a on thekcross bar 23 lying adjacent one yedge ofthe slotr 32 .and alsobythe ange 24aadjacent the corresponding edge of the crossbar 2,4. f'ihe edge of the cross '.bar 245bounding the slot 32 is provided with an intermediate strap-engaging surface.33 which is inclined in the same direction asthe inclined fsurrace25 'of the frame I5 for` co-operation therewith to. gripthe strap threaded through the slot 532 and` therebetween 'in adjusted positions. It may be desirable to augment the clamping,action.lof..fthe yco-operating .inclined surfaces .by the .raised portions 34 and 35 in the path of travel of the relative Imovement of the frame ymembersr so thatthe inner edge of the inclined portion 25 may buttythereagainst and distort the strapaslshown more particularly in Fig. 2.

The vframes are directed vin their relative longitudinal movements by the provision of ledgesv 36 andV 3E' .which are. preferably .f formed integrally with the side bars .Ill and I8, repectively, of the frame I5, the ledgesyeXtending in av direction'inwardly toward each other :to form opposed chan.-

nelswhen `viewed. 'in icross section. The strap 28 is threaded through .the.slot.,32 .of the frame I6 and thence over the erossrfbar- 24`andbeneath *the tongue-3|; the .freel'nd 28a. lying beneath 0 kthe overlying irame I5. `Vihentension is had on the strap 28, the bib. 38,y having. a ring-shaped "supporting member detachably received in the CQ-Operating hook-.shaped members'29 .and ED, f holds the `framefl'against Y, movement andy per- .mits thestrap tomove the .frame YIgE .relatively thereto. Such reiative movement between the frame members I5 and I 6 by the tensioning of vthe strap 28 causes a co-operation between the inclined surfaces 25 and 33 to clamp the strap, the direction of movement converging toward the inclined surface. The greater the tension on the strap, the tighter the clampingaction of the frames thereon, 1

`The resilient tongue 3i.,.which is preferably formed integrally with the inclined strap-engaging face 25, co-operates'with the hook-shaped portions 29 and 35 to releasably close the opening Yto the hook to prevent displacement of the supporting or ring member 39 of the bib of an overof the strap 28.

Referring now more particulariy to Figs. 7 and 8,- a further embodiment of this invention is shownfwherein the buckle comprises a pair of frame members di) and 4i, the frame member 40 all vand also prevents creeping of the free end 28a .being pueferably substantially ,rectangular in to accommodatethe Athickened edgeportions of a'strap 49. The other cross bar 45 is provided with ardepending loop havinga hook portion 5I for detachably receiving a supporting member or ring 52, the openingto the hookfshaped member being releasably closed by'a tongue 53 preferably formed integrally with -inclined portion 46 of the cross bar44 and extending therefrom in the direction of the loop to be. formed pref- ;erably out of thematerialbetween the loop.

.The framed! isv formed in substantially the sameinanner as the frame` I6 of the previousiy described modication except .that in the present described form the optional projections 34 and 35 of the frame .i6 are omitted. 'I'he side bars of the frame 4I are guided in thechannels formed by the ledges -54 extending inwardly in a direction toward eachother from the ,side-bars 42 and 43 to direct a relative longitudinal movement of the frames. One of the cross bars of the frame 4I is. provided. with a straprengaging face 55 which isv .inclined in the same direction asthe inclined face d6 A.of the frame 40 to co-operate therewith to clamp thestrap49 therebetween, the strap 49 extending through a strap receiving slot 56 in the frame 4I. and overthe inclined strap-engagling .face-55, with the free end .49a thereof extending beneath the overlying frame 40.

A tension. on :the strap 4.9 moves the frame 4I Vin alongituciinal direction against the resistance 'of .the `bibi'a'l attached by means of the ring 52 to the hookfshapedmemberlEl.. The resistance of the bib 5l fixes the frame .40 against movement, necessitating a movement kof theframe 4I in a directionto converge on the inclinedface whereby a clamping engagement of the strap is hadf between the` (3o-operating` ,strap-.engaging inclined surfaces .46 .and 55. Thetongue 53 releasably lcloses the opening into thehook-shaped loop .5I to prevent displacement of the ring 52 and also prevents creeping of the free end 49a.

of the slidably env1O,1the buckle therein shown comprises a pair of 'frame members 581and 59,.the frame member 58."-`

with entirely should it be desired to economizeon` material.

The cross bar 62 is provided with an intermediate strap-engagingV portion 64` which 'is inclined relatively to the plane of the frame 5,8,

portions 65 and 66 of the cross bar 62 lyingadjacent the edges of the inclined surface 644 and` being likewise inclined but to a greater angle `to accommodate the usual Vthickened edges of the strap. A tongue 61 is preferably formed integrally With the cross bar 62-and extends fromy the centrally inclined portionv 64 in a direction toward the other cross bar 63, a hook memberI 68 being formed on the end of the tongue for detachably receiving a supporting member or ring. The frame 59 is similar to the frame 4I of the just previously described embodiment, having side bars and connecting cross bars'deiining a slot 69 for receiving a strap.. A strap-engaging face 16 is provided on one ofthe cross bars adjacent the strap-receiving opening 69 which is inclined in the same direction as the inclined strap-engaging face '64 lto co-operate therewith and'to clampingly engage the strap.y The strap is threaded through the strap-receiving slot 69 and thence between the strap-engagingfaces64I-A and 18 to extend beneath the overlyingA frame 58.

TheV tongue 61 and integrally formed hook-shaped portion 68 co-operate to prevent creeping of the strap threaded between the frames, the hook 68 receiving the ring or supporting member' of the bib of an overall, or the like.

While several embodimentsfof` this invention are herein shown and described, it isk to Vbe understood that various modications thereof may be apparent to those skilled in the Aart Without departing from the spirit and scope of this invention and, therefore, the same is only to be limited by the scope of the prior art and the appended claims.
